BSPWM, laptop has 1920x1080 resolution, external screen has 1680x1050.
xrandr --output DP-1 1680x1050 cuts image, if I change resolution to 1920x1080, I get "full" image, but quality is just bad.
I have another machine with XFCE, it's display utility does the trick and I wonder can I achieve smth similar on BSPWM with some simple console command?
Defaults for herbstluftwm? Sure, but what'd be helpful if to translate a bspwm config. Are you using sxhkd?
I can't help with VM stuff; I'm not experienced with them.
Post your bspwm and sxhkd configs.
Yes.
It's easy way to learn things without fear to break something, can herbstluftwm use sxhkd?
Easily but why?
